Abstract

MÉTODOS E APARELHOS PARA TÉCNICAS DE MANIPULAÇÃO DE OCLUSÃO. A presente divulgação refere-se a métodos e aparelhos para processamento gráfico. O aparelho pode determinar um mapa de profundidade combinado com base em pelo menos uma malha 3DRU, um mapa DFS e uma pose de exibição. O aparelho também pode determinar um ou mais buffers de olho e de profundidade reprojetados com base em pelo menos um ou mais buffers de olho, um ou mais buffers de profundidade, um ou mais parâmetros de caixa delimitadora e de urdidura e a pose de exibição. Além disso, o aparelho pode comunicar pelo menos um quadro composto com base no mapa de profundidade combinado e um ou mais buffers de olho e de profundidade reprojetados. O aparelho também pode determinar pelo menos um quadro composto com base no mapa de profundidade combinado e um ou mais buffers de olhos e de profundidade reprojetados. O aparelho também pode combinar a malha 3DRU, o mapa DFS e a pose de exibição.METHODS AND APPARATUS FOR OCCLUSION MANIPULATION TECHNIQUES. The present disclosure relates to methods and apparatus for graphics processing. The apparatus can determine a combined depth map based on at least a 3DRU mesh, a DFS map and a display pose. The instrument may also determine one or more reprojected eye and depth buffers based on at least one or more eye buffers, one or more depth buffers, one or more bounding box and warp parameters, and the display pose. In addition, the apparatus may report at least one composite frame based on the combined depth map and one or more reprojected eye and depth buffers. The instrument can also determine at least one composite frame based on the combined depth map and one or more reprojected eye and depth buffers. The device can also combine 3DRU mesh, DFS map and display pose.
